A method for decoding a video bitstream is disclosed. The method comprises: entropy decoding a first portion of a video bitstream, wherein first portion of video bitstream is associated with a video frame, thereby producing a first portion of decoded data; entropy decoding a second portion of video bitstream, wherein second portion of video bitstream is associated with video frame, thereby producing a second portion of decoded data, wherein entropy decoding second portion of video bitstream is independent of entropy decoding first portion of video bitstream; and reconstructing a first portion of video frame associated with video bitstream using first portion of decoded data and second portion of decoded data.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for decoding video data, the method comprising: receiving a video bitstream, the video bitstream including plurality of pictures, the plurality of pictures including: a first picture with a plurality of blocks of samples that are entropy encoded; and a plurality of headers associated with the plurality of pictures, the plurality of headers including a first header associated with the first picture and a second header associated with the first picture, wherein the second header is different from the first header and shares most of attributes with the first header; obtaining, from the video bitstream the first header and the second header; examining value of a one bit parameter associated with each of the first header and the second header; and in response to the examining, determining that the value of the one bit parameter for the first header is set to 0 to indicate that the first header is a regular header, and the value of the one bit parameter for the second header indicates that the second header is not a regular header.
2. The method of claim 1 , wherein a size of the second header is smaller than a size of the first header.
3. An apparatus for decoding video data, the apparatus comprising: one or more processors; and one or more computer-readable media storing instructions that, when executed, cause the one or more processors to perform operations comprising: receiving a video bitstream, the video bitstream including plurality of pictures, the plurality of pictures including: a first picture with a plurality of blocks of samples that are entropy encoded; and a plurality of headers associated with the plurality of pictures, the plurality of headers including a first header associated with the first picture and a second header associated with the first picture, wherein the second header is different from the first header and shares most of attributes with the first header; obtaining, from the video bitstream the first header and the second header; examining value of a one bit parameter associated with each of the first header and the second header; and in response to the examining, determining that the value of the one bit parameter for the first header is set to 0 to indicate that the first header is a regular header, and the value of the one bit parameter for the second header indicates that the second header is not a regular header.
4. The apparatus of claim 3 , wherein a size of the second header is smaller than a size of the first header.
